CVR06FD - Roller Conveyor Oven

LEWCO Conveyor Ovens offer higher throughput compared to batch ovens, resulting in labor savings through increased material handling effciency. These ovens are suitable for a variety of applications such as heat-treating, curing, and drying. Roller conveyor ovens sometimes referred to as roller bed ovens have the heaviest load capacity. A series of rollers, mounted to bearings with sprockets on one end are driven by a common drive chain (or series of chain loops) connected to a gear motor. This conveyor design can also provide zoned accumulation, allowing product to accumulate inside the oven. Each unit comes complete with a one year warranty and is fully assembled, wired, and tested prior to shipment. All LEWCO Conveyor Ovens are manufactured to meet the requirements of NFPA 86.

Dual (Combination) Airflow: Hot air is supplied from both of the side walls and returned through a top plenum.

Input Voltage

Standard: 480/3/60. Please consult factory for additional options.

Control System

Conveyor oven control systems include variable speed conveyor drives that can be operated in either continuous or timed index mode (0.50 - 2.00 F.P.M.). Also includes a single set-point process temperature controller and redundant high-limit controller. Circulation fan(s) and exhaust fan(s) include air proving circuits that are electrically interlocked with the heating circuit. All controls are housed in a NEMA 12 enclosure employing a full voltage lockable disconnect switch. Controls are wired to NFPA 70 and 79 electrical standards. Other third party certifications available.

Optional:

Data Logger

Multiple input digital data logger continuously records temperature and other process data. Allows downloading of digital data files through USB or Ethernet connection. Data can also be viewed on a full color display or on a web server when connected to a network.

Zero Speed Switch for Fans

PLC

Programmable Logic Controller for processes with numerous inputs and outputs; or requiring automation of material handling equipment. The PLC can also allow for Ethernet connectivity for remote system monitoring.

Touchscreen HMI

Human Machine Interface provides the operator easy access and control of different parts of the equipment. Allows real time monitoring and provides feedback of the process in a visual, easy to read format.

LEWCO Roller Conveyor Ovens are available in several configurations and sizes. We invite you to try our Product Configurator to get detailed information regarding workspace height, width, and length options; as well as overall length, roller width, product dwell time, air changes per minute, heat capacity and circulation fan capacity.

LEWCO conveyor ovens are designed and manufactured to industry standards. Our engineers regularly work to keep updated with the latest revisions in industry codes. If there is a specific industry standard or code compliance that you require for your process heating application, please contact one of our highly knowledgeable applications engineers to learn how LEWCO can help!

About NFPA 86

The National Fire Protection Association’s standard, NFPA 86, documents the guidelines for the safe operation of industrial ovens and furnaces. All LEWCO ovens are designed and manufactured to meet the requirements of this standard. Oven and furnaces in which flammable volatiles or combustible materials are present in the work space are classified by NFPA 86 as “Class A.” Similarly, ovens and furnaces in which no flammable volatiles or combustible materials are present are classified as “Class B.” Due to the risk of fire or explosion, NFPA 86 requires specific safety equipment for all Class A ovens and furnaces. Fuel gas-fired ovens and furnaces also require safety equipment.
